Ultracompact Electroabsorption Modulators Based on Tunable Epsilon-Near-Zero-Slot Waveguides

IEEE Photonics Journal, 2012
We present a promising application of epsilon-near-zero (ENZ) materials in optical modulators. When a thin ENZ film is sandwiched in a single-mode waveguide, an ENZ-slot waveguide is formed, where the absorption can be greatly enhanced.

High‐Efficiency Acousto‐Optic Modulation on Non‐Suspended Thin‐Film Lithium Tantalate

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
We demonstrate high‐efficiency acousto‐optic modulation on a non‐suspended thin‐film lithium tantalate (LTOI) platform. By engineering acoustic modes within high‐Q resonators, the devices achieve low half‐wave voltage‐length products. This work establishes LTOI as a robust, scalable solution for integrated microwave‐photonics, combining strong ...

Effects of pressure and inter-electrode distance on deposition of nanocrystalline silicon under high pressure conditions [PDF]

, 2010
Pressure (p) and inter-electrode distance (d) are important parameters in the process of depositing hydrogenated nanocrystalline silicon (nc-Si:H) by very high frequency plasma enhanced chemical vapour deposition (VHF PECVD).

Design and Analysis of a Miniature Intensity Modulator Based on a Silicon-Polymer-Metal Hybrid Plasmonic Waveguide

IEEE Photonics Journal, 2014
We propose a miniature optical intensity modulator based on a silicon-polymer-metal hybrid plasmonic waveguide. Benefiting from the high mode confinement of hybrid plasmonic waveguide and the high linear electro-optic effect of polymer material, the ...

Rolling‐Enabled Nonplanar Heterogeneous Integration for Polarization‐Diverse Nanolasers on Silicon Photonics

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Rolling‐enabled transfer printing introduces mechanical orientation as a new degree of freedom for heterogeneous silicon photonics. A conventional TE‐like photonic‐crystal nanobeam laser is mechanically rotated by 90° to selectively couple with the TM‐like mode of a silicon waveguide, enabling polarization‐diverse functionality without redesigning the ...

A silicon single-electron pump with tunable electrostatic confinement

, 2015
Nanoscale single-electron pumps could serve as the realization of a new quantum standard of electrical current. Here, a silicon quantum dot with tunable tunnel barriers is used as a source of quantized current.

Probing Strong Coupling in Core–Shell Nanoparticles With Fast Electron Beams

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
An exact analytic formalism for evaluating electron‐energy loss and cathodoluminescence probabilities for core–shell nanoparticles explored by electron‐beam spectroscopies is derived. The formalism is exploited to understand strong exciton–plasmon and exciton–Mie mode coupling in nanophotonic architectures.

High-Efficiency Metamaterial-Engineered Grating Couplers for Silicon Nitride Photonics

Nanomaterials
Silicon nitride (Si3N4) is an ideal candidate for the development of low-loss photonic integrated circuits. However, efficient light coupling between standard optical fibers and Si3N4 chips remains a significant challenge.

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, Volume 36, Issue 75, 17 September 2026.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc
